How do molecules get into cells?
Diffusion
Osmosis
with concentration gradient
water flows from higher concentrations of solute to lower concentrations of solute
Simple Diffusion
with concentration gradient
no proteins
Facilitated Diffusion
with concentration gradientw
uses channel proteins
Active diffusion
against concentration gradient
requires energy
uses transport proteins
Cell Membrane
Semi-permeable
only lets through select things
phospholipid bilayer
tail is hydrophobic
head is hydrophilic
has proteins embedded
used for diffusion or transport
